Added support for .DIVX files. File types supported in this version include: .divx, .flv, .mkv, .mka, .vob, and .ac3. All icons and .plist changes are included in this package. Just run the script. Be sure to associate your file types to open with Quicktime automatically. -divx support added by K3vinmartin

We could do something like what Flip4Mac does and have a mini application that handles the various media types and simply tells QuickTime player to open them. Though I don't know if LaunchServices? would pick up on it if it was inside the prefpane bundle.

I've manually modified QuickTime Player's Info.plit to handle Perian file types with correct icons.
You must put new .icns files inside the Resources folder (in the QuickTime Player application bundle) and add new types in the Info.plist file (also inside the bundle).
In attachment my modified Info.plist file of version 7.1.6 of QuickTime Player.

Besides replacing Info.plist, you will need to run /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -f /Applications/QuickTime\ Player.app/ in the Terminal (to update Launch Services' cache of Info.plist) and relaunch the Finder in order for the changes to take effect. Touching the file may do as well (but I've not tried this).

Some kind of replacement icons for formats such as FLV and MKV which QuickTime doesn't have icons for?

This is a great little script! I have modified the code for version PerianAddFile4.zip to also include .divx file associations. Hope nobody minds. For future reference to all noobs to this site, ALL you need is to download is the latest PerianAddFile?.zip script. All icons and plist changes are added and made automatically. Once the script is run it will ask to relaunch finder. Make sure that you associate the particular file type movies to by default open with Quicktime. You can does this: Right Click the particular movie file you want associated>Select GetInfo?>Select Quicktime using the dropdown menu under the Open With: subsection>Select Change All Button>log out then log back in or restart Finder.

What we need is a basic "Perian" Application that has all the plist settings and icons, however the application is merely a script that passes the file onto quicktime and closes itself. This is how Flip4Mac got around this problem and this should really only take a moment or two.

Replying to tagscuderia:
Sorry guys, had an issue submitting my comment. I've used 'Perian Importer' and it's worked, the icons got moved across but the info.plist file did not so I downloaded the second version and moved that across. However, I still don't get quick look support which is a shame. I was wondering if anyone else is having trouble and if anyone's found a solution? I think it would be good to keep this as is rather than mimicking Flip4Mac. I hope this gets into the next Perian build.

My upload has a few failed attempts at creating a simple way of interacting with the program. The info.plist file has three UTIs defined: two for the Matroska formats (mka,mkv), and one for the Flash Video format. The Document Types definition takes advantage of the UTI if available, so don't be alarmed if there are no filename extensions or mime-types: They're in the UTI. The names are stored in the infoplist.strings file to make localization easier. The application in there is basically an AppleScript? droplet with its info.plist file altered. The main Application Icon is the perian icon, and the file icons were taken from this ticket. As in the file description, thanks dak180 for the AppleScript?.

Now for info about my new version: This one will actually link, compile, and work. It needs to link against AppleScriptKit? and Cocoa.

It also uses a different style of nib (xib extension before compiled) that may or may not work with older versions of Xcode. And yes, it is needed in order to run. Again, UTIs are defined for Matroska(mka, mkv) and flash video(flv, f4v) containers. I did fix the UTIs so that the icon is properly defined in it, but with how I set up the plist it doesn't matter.
